Planned program activities

The 2021—22 fire ant treatment season has started.

Our 2021–22 fire ant treatment season is now underway in South East Queensland.

Fire ant treatment is completed during the warmer months of the year, typically September to June.

What is planned program treatment?

Each year, our teams are tasked with implementing a range of activities that will help us achieve our 10-year Eradication Plan.

The timing, frequency and target areas of these activities vary however they always comprise of:

We typically complete treatment in the warmer months and surveillance in winter.

You will be notified if your property is scheduled for treatment. This may be in the form of a brochure in your mailbox, letter, email or phone call. It is important that we treat all properties — one untreated nest could be the difference between infestation and fire ant eradication in your area.

If your property is scheduled for fire ant treatment it is important to tell us if you have potential access issues or hazards.


Planned treatment 2021–22

This year we are prioritising treatment and surveillance in the areas shown on the map below:

Program and Community Treatment Areas Map 2021-2022

The areas shown on the map above will receive the following treatment in the 2021–22. We aim to deliver planned treatment on 352,000 hectares (ha) this year — comprised of 1–4 treatment rounds in each of the target areas.

Use the key below to learn more about what fire ant activities we are completing in your suburb, when and why.

Clearance areas

  • Lockyer Valley, Scenic Rim and parts of Ipswich local government areas.
  • Carried out between September and June.
  • Broadscale treatment is now complete.  Between 2 and 3 rounds of treatment were applied to clearance areas. The number of treatments increased for areas considered a higher risk.
  • Targeted surveillance has commenced, and we are performing spot treatment as needed.
  • New nests are treated as a priority to prevent reinfestation.

  • Covers a 4 km strip along the eastern side of Area 2 in Ipswich, Somerset and City of Logan local government areas, spanning from Undullah to Patrick Estate.
  • Covers a 2km wide strip outside Area 2—from Undullah to Patrick Estate.
  • Up to 2 rounds of treatment covering approximately 22,250 ha per round.
  • Multiple treatments will be completed in this area between September 2021 and June 2022.
  • An overlap reduces the risk of new nests in already treated areas.

  • Up to 2 rounds of treatment covering approximately 15,450 ha.
  • Covers a 2km wide strip on the western side of the eastern overlap in Ipswich, Somerset and City of Logan local government areas, spanning from Undullah to Rifle Range.
  • Multiple treatments will be completed in this area between September 2021 and June 2022.
  • An overlap reduces the risk of new nests in already treated areas.
Containment areas

  • Up to 2 rounds of treatment are planned for the southern suppression (south) area.
  • Planned treatment includes approximately 31,950 ha.
  • Covers a 2km wide strip along the southern boundary of the operational area.
  • Adjoins the eastern overlap at Wyaralong and continues east to the suburb of Mount Nathan.
  • At least 1 treatment will be completed in this area between November 2021 and May 2022.
  • Reduces the risk of infestation from moving further south.

  • Up to 1 round of treatment is planned for the southern suppression (north) area.
  • Planned treatment includes approximately 21,900 ha.
  • Covers a 3km wide strip along the northern boundary of the southern suppression (south) area.
  • Treatment covers the suburb of Flinders Lakes and continues east to Benobble and Wonglepong.
  • At least 1 treatment will be completed in this area between November 2021 and May 2022.
  • Reduces the level of infestation in the area growing and spreading east and further south.

  • Fire ant nests found outside of our operational boundary.
  • New nests are treated as a matter of priority.
  • The area in which nests are found is also checked extensively for additional nests. Any nests found are treated immediately.
  • Reduces the risk of spread and ensures South East Queensland’s fire ant population is contained.
Other areas

Suburbs targeted as part of our current community fire ant treatment projects:

  • Calamvale ward, Brisbane
  • Gold Coast
  • Tamborine Mountain

  • Covers all areas of South East Queensland not scheduled to receive planned treatment in 2021–22.
  • Property owners, tenants and managers are legally required to look for and report fire ants within 24 hours (Biosecurity Act 2014).
  • Positive detections can be managed in one or more ways.

Eradication treatment and eradication clearance

Planned treatment areas for 2021-22 include greater Ipswich, western Logan, new parts of Lockyer Valley, Somerset, and Scenic Rim.

Our focus is ensuring that the progress we make is not reversed. Preventing the spread of ants outside of the current infestation area is also a priority. Some suburbs which have previously received treatment will be treated again this year. This protects the previous eradication areas from new fire ant queens flying into areas that were treated in the last round.

Ground and aerial treatment activities are planned. Several rounds of bait is applied to all properties within the eradication treatment area.

If you live in an area that is not currently being treated, you can treat fire ants yourself.

If you live outside a biosecurity zone and have seen fire ants, please immediately call 13 25 23 or report online.


Surveillance activities

Containment surveillance aims to reduce the spread of fire ants. We conduct three types of surveillance to determine the presence or absence of fire ants: sentinel, targeted and clearance surveillance.

Surveillance activities are also undertaken to ensure treated areas are free from fire ants.

The total area planned for sentinel surveillance is up to 1,300 ha, covering approximately 10 ha of suitable habitat per site over 130 sites.

Sentinel sites monitor the presence or absence of fire ants in areas considered highly suitable habitats for fire ants.

Infestation found on a sentinel site will trigger treatment, surveillance, and tracing for both the site and the surrounding area.

The total area for planned targeted surveillance is approximately 4,200 ha.

Site selection will be based on previous boundary and significant detections, previous surveillance, location, and number of detections.

Clearance surveillance will be conducted in previous treatment eradication areas.


Self-treatment options

This season, people across South East Queensland are working with us in community fire ant treatment projects to help fight fire ants in their backyards and neighbourhoods.

In the 2021-22 treatment season we are exploring how to best treat the pest in urban and peri-urban neighbourhoods in:

Residents, schools, sports clubs, farmers, and operators of public spaces anywhere in South East Queensland can also treat their properties using fire ant bait.

A range of local and online retailers and pest chemical suppliers sell fire ant bait. These are easy to use, safe, and only need to be applied a couple of times throughout the year.
